It would be for most engines. That's why after the first season of running I had to tear them both down and open the ring gaps. With the kb silvolites the speced end gap for super charged marine big block is .038 which is about where I am at. The top ring is set high on the piston which is why the large gaps. I have near zero blowby after three seasons of hard running. Also, mathmatically speaking, an end gap of .028 or .038 is miniscule in relation to total piston clearance area. I like my gaps big.
